IMPROVEMENT IN COOK-STOVES.

Specification forming part of Letters Patent No. 50,072, dated September 19, 1865.

To all whom it may concern:

Be it known that I, MARcUs L. HoR'roN, of Claremont, in the county ot' Sullivan and State of New Hampshire, have invented a new and Improved Mode of Conveying Heated Air to the Elevated Oven of a- Cooking-Stove; and I do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in providing the lower part of the oven with a con ducting-pipe and cap combined, which pipe will convey heated air into the oven to equalize its temperature and act as an absorbent of moisture, and an improved air-ue the whole width ofthe stove, to allow the air to come 1n contact with more heating-surface of the stove lto increase its temperature and draft To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, Figure l is a top View ofthe stove with the oven removed. Fig. 2 is a section through the lire-chamber, tire-nues, oven, &c., on the line 2 2, Fig. 1. Fig. 3 is a section through the hot-air ues on the lines 3 3, Fig. 1. Fig. et is a cross-section through the tire-chamber,'showing the gratebars. Fig. 5 is a section through the oven on the line l l, Figs. l and 3. The black arrows indicate the direction of the aircurren ts. The red arrows show the {ire-currents.

M is the tire-chamber.

B B are the hollow grate-bars, the air-spaces in which communicate with the external air through the holes D, Figs. 2, 3, and 4, and with the space S behind the back plate ot' the irechamber. From this space S a flue, c c c, the whole width of the stove, extends back to and communicates through the pipe E into the oren It, and with the dues F F inclosing the oven lt entirely, which establish a connection From the Hue F F, on the top ot' the oven, are openings J J, through which the heated air may be carried through pipes or ues to other places.

Extending back from the re-chamber on each side of the -stove are the re-tlues m m, communicating through openings u with the ues G, also surrounding and inclosing the oven R, and occupying the space between its sides and the hot-air hues F F. A collar, F',

affords the means of connecting the dues G G with the chimney by a pipe.

In the center of the top of the oven is a ventilator, H, opening into the ues G G and covered with a hood, O, Figs. 3 and 5, to keep anything from falling in from the chimney, and furnished with a valve, y, on the inside ofthe oven 'for regulation or complete stoppage. The flame and gaseous products of combustion pass along the tiues fm through the openings n into the ues G G on each side of the oven, and pass up over it into the chimney through the opening I. At the same time cold air rushes in through the openings D into the hollow grate- 4bars, and passes into and along the due C until a portion rises into the oven through the pipe E. The rest rises into the flues F F, to be conducted away from the opening J above the oven to wherever it may be desired. The hor. air does not fall in temperature in its passage through its fines, as it is kept hot by its prox imity to the tire-dues. f,

I am aware that a stove has been made. with the grate-bars B, space S, a Hue about onethird the width ofthe stove ip the center, nues F F., with openings each side ot the oven R for the heated air to enter it from the tlues F F, and their various connections, except what I now claim-viz., the pipe E, for conducting the heated air into the oven from the tlues C, so that the spaces at each side ofthe oven can be omitted,in order that the air which is conveyed away for the purpose ot'giviug warmth elsewhere may be free from the smoke and gases in the oven during the baking process; also, the cap A, Figs. 3 and 5, combined with the pipe E, which cap is toprevent anything from falling into the flue C from the oven; and also the improved :tlue C, extending the whole width of' the stove, thereby increasing' the draft of the air-currents as well as exposing them to more heating-surface of the stove.

Having thus fully described my invention,

and distinguished between what is admitted to be old and what is claimed to bc the im provement, what I claim as new, and desire to secure by Letters Patent, is-

The pipe E with cap A and improved flue C, as arranged and in combination, operating as described, and for the purposes set forth.
